Description

For tube drawing and the device of push wire harness

Technical field

It the utility model is related to for the feed-through device of steel strand wires, sebific duct extracting apparatus in high ferro or science of bridge building, especially It is the device for tube drawing and push wire harness.

Background technology

High ferro precast beam is the steel strand wires by being through in beam body " hyperbola preformed hole ", is produced by tensioning process powerful Prestressing force, to bear all loads including beam body deadweight.

It is first to be penetrated in framework of steel reinforcement " rubber pulling rod rod " in precast beam construction（Abbreviation sebific duct）；In concrete casting After initial set, sebific duct is extracted in time and forms preformed hole；Then a number of steel strand wires are penetrated；The work such as tensioning, anchoring is carried out again Industry, this just needs " drawbench ", " cable machine " special equipment to carry out coordinative construction.

" tube drawing " operation present situation at present：The drawbench that high ferro beam making field generally uses, it is to utilize " pinch roller rotation " mostly Frictional force carrys out withdrawing sebific duct, and this mechanism, only by unconfined increasing normal pressure, not only makes to produce enough taking out force Into reactive loss is excessive, fault rate is extra-high, and because limit of friction taking out force is relatively low, often occur " skid damage sebific duct " Phenomenon, actual withdrawing speed can only be also controlled at less than 16 meters per minute.

" reeve " at present operation present situation：China's high ferro beam making field up to the present almost all using " single to reeve " Technique, due to intrinsic " spiral " structure of steel strand surface, steel strand wires can be forced to produce rotation during penetrating, generation can not " the unordered winding " of precognition, cause, with group steel strand wires physical length difference, steel strand wires unbalance stress to be caused in tension process, is managed By the bearing capacity for above reducing beam body；What What is more is the confined space that " unordered winding " has tied up hole, on penetrating During portion's preformed hole, by " hyperbola " overlaying influence that sagging amplitude is larger, the steel strand wires of rotation are forced by force from beam body or adjacent Drilled out in preformed hole, cause last root steel strand wires at all can not be by, operator have to be by normally blocking；In other end hand Work, which penetrates half steel strand wires, makes up the number or amount and plays tricks, though such case category is extremely rare, can give the high ferro circuit of project of vital and lasting importance really Bury unpredictable " potential safety hazard "！

The problem of being existed based on single technique of reeving, for the construction quality of accurate control bridge, existing high ferro industry is actively advocated Lead：Combed to compile by the manufacture of production upstream producer and made in order, tie up fixed " finished product steel wire bundle ", then by downstream construction enterprises Directly buying " finished product steel strand wires boundling " is reeved, and problem is that beam making field " applicable equipment of reeving " cannot solve for a long time Certainly.

In cable machine field, have in the prior art：

One, Chinese utility model patent, patent name " a kind of double dynamical pusher for conveying finished product steel wire bundle ", patent Application number 201510387497.1, date of publication are on November 04th, 2015.Disclose a kind of for pushing finished product steel wire bundle Equipment.

This equipment is that Caterpillar transmission mechanism is set on two relatively-movable frameworks, and Caterpillar transmission mechanism includes chain Bar and interval are installed in the crawler belt slips on chain, and finished product steel wire bundle is held tightly from both sides by corresponding multiple crawler belt slips, Under the driving of Caterpillar transmission mechanism, finished product steel wire bundle is conveyed.

Flexible Transmission feature of this mechanism due to chain in itself, input, output end only in chain are carried by drive sprocket For transverse clamping force, and the crawler belt slips between two sprocket wheels, because no cross-brace does not almost have clamping force, cause slips and Finished product steel wire bundle Relative sliding, causes slips accelerated wear test；Inevitably sagging factor is horizontally disposed with additionally, due to chain, Worn with each portion of chain, card chain fracture accident easily occurs when chain dallies.

Two, Chinese utility model patent, patent name " steel strand integral bundle cable machine ", the patent No. ZL201520756329.0, date of publication are to disclose a kind of equipment for pushing finished product steel wire bundle on January 13rd, 2016.This Kind equipment machine weighs 3.1 tons, and 6 meters of peripheral lengths, 1.7 meters of * width, mobile phase is when inconvenience between the beam platform of high ferro beam making field.

Due to many disadvantages of above-mentioned patented product, in China, high ferro beam making field cannot arrive popularization all the time, that is to say, that Even to this day untill, a undisputable fact is exactly：" " the single work of reeving that China's high ferro beam making field still still uses at present Skill ".
